Four models of the new, bigger 7-series BMW sedans are available: V-8, and V-12 versions come in two different body lengths each. As you\'d expect from BMW, everything is more refined than in last year\'s big sedan, which was introduced in the U.S. in the spring of 1987. One example: the side mirror housings are designed aerodynamically to keep the side windows clean. The body has been made more aerodynamic, too, with a coefficient of drag of just 0.32 instead of the 0.34 Cd of the previous 7s. Less wind noise and fewer trips to the car wash should be the result. Underneath, the new platform is stiffer, and BMW claims a natural frequency of the car to be 26 cycles per second, slightly better than the Oldsmobile Aurora and Mercedes E-class sedans, which are benchmarks in body stiffness.
